1-2. oil channel structures
Here, by the oil channel structures of comparing embodiment and the structure of the prior art.First, the supply of the structure of the prior art
Pipe 300 is installed into around the outside of differential casing 51, so as to which the oil from mechanical oil pump 6 is supplied to differential gear machine
Structure 5.Further, since differential gear mechanism 5 is arranged on the 3rd axis R3On, so supply pipe 300 extends upwardly to the 3rd axis R3
Periphery, so as to around first axle R1With the second axis R2Outside, and along housing 2 wall surface extend.For this reason, in existing skill
In the supply pipe 300 of art, oil circuit length, and the pressure loss oily caused by oil circuit length becomes larger.Thus, in order to shorten
Oil circuit length, considers to form the oil circuit (hereinafter referred to as " most short oil road ") 200 of shortest path.
Most short oil road 200 be changed into its on the whole from mechanical oil pump 6 towards differential gear mechanism 5 be linear path.
However, around fuel feeding destination there are many elements (surrounding member), such as bearing and ribs, and it is complicated.It is for this reason, difficult
To set discharge port by the position that fuel feeding destination can be provided in oil, and linear oil circuit is connected to discharge
The position of port links together with mechanical oil pump 6 and realizes most short oil road 200.Then, consider that linear oil circuit is connected to keep away
Open surrounding member.However, in this case, wherein oil circuit suddenly curved right-angle bending is formed, thus oil circuit shape causes
The oily pressure loss become larger.Thus, the supply oil circuit 100 of the present embodiment is configured to around fuel feeding destination offer curves oil
Road, so as to reduce the pressure loss oily caused by oil circuit shape, and is realized more closer than the supply pipe 300 of the prior art most short
The path of oil circuit 200, so as to reduce the pressure loss caused by oil circuit length.
The supply oil circuit 100 of the present embodiment is configured to that oil is pumped to difference from mechanical oil pump 6 via cylindrical baffle 10
Fast device gear mechanism 5.Baffle 10 is the baffle for having oil circuit, wherein being formed in the oil circuit extended in the circumferential direction in plate.Separately
Outside, baffle 10 is arranged around fuel feeding destination.For this reason, in oil circuit 100 is supplied, the circumferential direction side inside baffle 10 can be used
Oil is pumped upwards about the oil circuit of fuel feeding destination extension.That is, in circumferential direction around fuel feeding destination extension oil circuit by conduct
The baffle 10 of the surrounding member of fuel feeding destination is formed.Thus, the oily pressure loss can reduce caused by oil circuit shape.Separately
Outside, supply oil circuit 100 is changed into the path on most short oil road 200 more closer than the supply pipe 300 of the prior art.As shown in fig. 1, exist
When from axial direction, supply pipe 300 is arranged on rotation axis (first axle R1, the second axis R2With the 3rd axis R3) exterior.So
And supply oil circuit 100 and be provided in first axle R of the interior of rotating shaft i.e. on fuel feeding source1, and on the side of fuel feeding destination
Three axis R3Between (and further in the second axis R2With the 3rd axis R3Between) pass through.For this reason, the oil circuit length of supply oil circuit 100
It is changed into shorter than the length of supply pipe 300.Thus, it is possible to reduce the pressure loss oily caused by oil circuit length.
2. baffle and the arrangement of fuel feeding part
By referring to figs. 2 and 3 the arrangement of description baffle 10 and fuel feeding destination.Fig. 2 is the arrangement for showing baffle 10
Schematic diagram.Fig. 3 is the sectional view for the internal structure for schematically showing housing 2.In addition, differential gear not shown in Fig. 2
Mechanism 5, and a part for housing 2 is shown.
The arrangement of 2-1. baffles
Baffle 10 is by around the 3rd axes O3The inside of housing 2 is arranged in, and to have predetermined length in the axial direction
Tubular form formed.In addition, as shown in Figure 3, baffle 10 is attached to the fixing component of the inner wall of housing 2, and by cloth
Put between differential casing 51 and housing 2.Differential gear mechanism 5 including differential casing 51 is fuel feeding destination.That is,
Baffle 10 is attached to the inner wall of housing 2 around fuel feeding destination.

4. the flowing of oil
Here, the oily flowing by tray manifold 130 will be described.The oil of tray manifold 130 has been flowed into from supply port 150
Pass radially inwardly through the introducing portion of the first oil circuit 131.Then, flowed into from the introducing portion of the first oil circuit 131 main
Partial oil flows through the first oil circuit 131 in the circumferential direction of baffle 10.Since baffle 10 around fuel feeding destination is attached to housing 2
Inner wall, so flow through the first oil circuit 131 oil in circumferential direction around fuel feeding destination flow.In addition, flow through the first oil circuit
The oil of 131 major part branch and flow to second at branch location between the first oil circuit 131 and the 3rd oil circuit 133
132 side of oil circuit and 133 side of the 3rd oil circuit.
The oil that 132 side of the second oil circuit has been flowed to from branch location is flowed into via connected component 123 from the first oil circuit 131
In second oil circuit 132.Then, the oil for having flowed into the second oil circuit 132 is discharged from the first discharge port 161, or from conduct
The through hole 118 of 3rd discharge port is discharged.On the other hand, the oil of 133 side of the 3rd oil circuit is flow to from branch location radially
The 3rd oil circuit 133 is outwards flowed through, and is discharged from the second discharge port 162.
Then, the oil discharged from the first discharge port 161 is towards the first fuel feeding destination A's outside baffle 10
First differential bearing 55A flows.Entered the second fuel feeding on single axis by the oil stream discharged from the second discharge port 162
In the pinion mechanism 4 of destination B inside included countershaft 41.Due to the first discharge port 161 and the second discharge port 162
Reciprocally it is open in the axial direction, so tray manifold 130 can allow for arranging on the different directions of oil in the axial direction
Go out.In addition, discharged from the through hole 118 as the 3rd discharge port oily towards the 3rd fuel feeding inside tubular portion 111
The differential pinion 53 and differential side gear 54 of destination C flows.
By this way, by setting the baffle 10 of the tray manifold 130 shared with fuel feeding destination, and difference is set
In different the first discharge ports 161 for needing oil site, the second discharge port 162 and through hole as the 3rd discharge port
118, lubricating oil can be easy to need oil site supplied to lubricating oil shortage.Thus, the number of oil circuit can be reduced, and be mended at the same time
Repaying needs the lubrication shortage of oil of oil site.For this reason, the manufacture cost of power transmission 1 can be suppressed.
As described above, in the oil channel structures of the embodiment, form supply oil circuit 100 a part tray manifold 130 around
Fuel feeding destination is formed in the baffle 10 for being attached to the inner wall of housing 2.Tray manifold 130 around fuel feeding destination in circumferential direction
Extension, and connected with discharge port 161,162, oil is supplied to fuel feeding destination.For this reason, it can use around fuel feeding purpose
Oil is pumped to fuel feeding destination by the tray manifold 130 that ground extends in circumferential direction.Thus, oily pressure caused by oil circuit shape
Loss can be reduced.In addition, the oil circuit length of supply oil circuit 100 can be shortened, and pressure oily caused by oil circuit length
Loss can be also reduced.Similarly, the negative of mechanical oil pump 6 can be reduced by reducing the pressure loss supplied in oil circuit 100
Lotus.Further, since the supply pipe that will be disposed in inside housing 2 can be reduced, so the number of part can be reduced, and energy
It is enough to reduce manufacture cost.In addition, the weight of housing 2 can reduce, i.e., the weight of power transmission 1 can reduce.Thus, move
